To all whom it may concern Be it known that I, PETER KRUsE, a citizen ofthe United States of America, residing in the borough of Brooklyn,county of. Kings, city and State of- New York, have invented c ertainnew and useful Improve,

ments in Machines for Seaming Heads .or Ends on Cans, of which thefollowing is a specification. v

TlllS lnvention relates to machines for seaming heads or ends on cans orcan bodies, and aims to provide improvements therein. The generalcharacteristics of the present invention resemble those set forth in myUnited States Patent No. 1,143,97 6, granted June 22, 1915. g Thepresent invention provides a machine which is readily adapted'forseaming heads Fig. 2 being a transverse sectional vie on the line IL-IIof Fig. 1.

11 designates a seaming ring and 15 an opposite seaming sector. One ofthese parts performs the first seaming operation and the other thesecond. One or both of these seamers is preferably rotatable.

The can bodies and ends are supported by suitable means, as chucks 7 and8, these means or chucks being displaceable to move the can bodles andends Into successive operation with the seamers. The chucks 7 and 8are'also preferably mounted upon a rotatable carrier, as'the plates 1and 2, the carrier acting to move the cans and ends from areceivingposition to. a discharge position.

The plates 1 and 2 may be conveniently fixed upon a shaft 3 rotated by asuitable pulley 4. and a train of gears 5.. As stated, one of theseamers, as the scanner 11, is rotatable, and to this end one of thecarriers, as the carrier 1, serves as a convenient support for thesupport 10 which carries the said seamer 11. The support 10 and seamingring 11 are rotated upon the carrier 1 by suitable gearing l2 and rack13, the gearing 12 being actuated from the drive shaft 14. Therotation-of the seamer 11 is ordinarily in the same direction as, andfaster than that of the carriers 1, 2 on which the chucks 7, S-arecarried, thecan and, assembled head being thereby given a rotation inthe same direction as it subsequently rolls on the seaming sector15fabout to be described. J

In my Patent 1,143,597 6 the seamer corresponding to the segment 15herein is shown as rotatably mounted upon thecarrier corresponding tothe carrier lherei'n. The seaming sector 15 might besimilarly arranged.Preferably, however, the seaming sector 15 is carried uponbrackets'16projecting from.

the frame of the machine. The seaming sector 15 is preferably removablyand adjustably mounted upon the brackets, and to thisend isprovided'with slots 15 through which the fastening bolts pass.

Operation: The seaming of heads or ends on cans is usually effected intwo operations, called the first seaming operation and the secondseaming operation. As here shown,

the first seaming operation. Can bodies and ends are fed to the machineby a suitable feed means 20, the bodies and ends being received and heldtogether by a pair of chucks 7 and 8 upon the carriers 1 and 2, one ofthe chucks being moved axially by a suitable cam 18. Attached to each ofthe chucks is a roller 21- adapted to contact at an appropriate timewith cam rails 22,22,

. the seaming ring 11 is adapted to perform fixed upon the frame of themachine. The

cam rails 22, 22 "act to bring the chucks,

and the can bodies and ends held between the chucks, into workingcontact with the seaming ring 11, which, as heretofore explained, isrotated-by suitable driving means upon the carrier 1. As the carriers 1and 2 carry the can forward the first seaming operation is performed.'When this first seaming. operation is completed the rollers 21,

come'into contact with other camrails 23, 23, upon the frame, whichshift the chucks and can bodies held thereby to bring the can bodies andpartially seamed ends thereon into operative contact with the seamingsector 15. They seaming sector 15 then acts to perform the secondseaming operation and complete the seaming of the head upon the canbody. It will be understood that the chucks are rotatably mounted intheir supports and hence allow the can bodies and ends to turn when theyare in contact with the seaming ring 11 and seaming sector 15. I
